A bit long winded please bear with me.

I have John Tregona b St Ives aged 50 a Newsagent in Plymouth Married Blind for 13 years. (c 1841)
Son Thomas J F age 13 b Plymouth (c 1878)
Daugh Elizabeth 7 (i think) b Westminster. (c 1884)

I believe these should be Trezona's.

BMD'S The closest I can find is Elizabeth Jane jul/au/sept 1883 Plymouth

NO Thomas in plymouth or London but
1880 in redruth Thomas Ap/may/jun
1881 in redruth Thomas H jul/au/sept
1878 redruth ap/may/jun William Thomas

But I think I have accounted for these in censuses etc.

At the moment I cannot find this family in either 1881 or 1901

in 1881 however there is a family as follows
Charlotte Treyona 31 Mar Head Dressmaker b Gloster
Agnes daugh 9 b westminster
John son 3 b westminster
Kate 3 month b Southwark

I have found the BMD entries for Charlotte Agnes 1871, Frederick John 1877, and Kate Miriam march 1881 all Trezona.

Is it possible that Frederick and Thomas J F are the same boy??

Where is John Trezona b c 1841 (blind) in 1881 and 1901?

Any thoughts or clues greatly appreciated.

Thankyou
